Description
Shutaro Kurusu, a 25-year-old A-class vampire, serves in the Imperial Army’s Code Zero unit as part of the Kongo Iron Soldier Plan. Once a wholesaler in Nihonbashi, his life shifted irrevocably after contracting the vampire virus, propelling him into a strategic diplomatic role for Japan. The stigmata marking his transformation—a bite scar on his neck—serves as a constant reminder of his dual existence.

Of average height with black hair swept from his forehead and piercing crimson eyes, he cuts a striking figure in Code Zero’s standard uniform, katana at his side. His demeanor, softened by a civilian past, defies military stereotypes, blending tactical precision with an unassuming gentleness. Though compassionate toward allies and civilians, his technical pacifism—avoiding lethal force to safeguard his fragile humanity—sometimes risks mission safety, testing his resolve against the specter of madness.

Bound by a childhood promise to journalist Aoi Shirase, who believes him dead after his Siberian deployment, his survival may hinge on that vow. Their relationship, steeped in theatrical motifs and tragic romantic undertones, orbits the chasm between his vampiric curse and her mortal life. Media adaptations amplify their separation through symbolic visuals, echoing timeless tales of star-crossed love.

Narratively, Shutaro evolves from a secondary figure in early arcs to a central protagonist following a catastrophic earthquake, wrestling with identity amid escalating conflict. Manga iterations delve deeper into Aoi’s grief and their unresolved bond, while anime versions streamline their connection without diminishing its emotional core.

Internally, he grapples with the lure of his vampiric powers against the terror of losing himself. Missions force harrowing choices, such as defending distrustful civilians, underscoring themes of morality and belonging in a world hostile to his kind. Heroic deeds under fire—like perilous rescues—and tense dynamics with Code Zero allies, who question his methods, highlight his struggle. Despite instilling primal fear in lower-ranked vampires, he wields restraint, setting him apart from ruthless peers.

Across stage, manga, and anime, Shutaro remains an enduring symbol of humanity amid supernatural chaos. His journey reflects the tug-of-war between duty and conscience, unfolding against a backdrop of historical upheaval and existential peril.
